The larger angle is 70 degrees.
Explicação
## Step 1Let's denote the larger angle as
and the smaller angle as
. According to the problem, the larger angle is 30 degrees more than twice the smaller angle. This can be written as the equation:###
## Step 2We also know that the sum of complementary angles is 90 degrees. Therefore, we can write another equation:###
## Step 3Now we have a system of two equations, which we can solve to find the values of
and
.## Step 4Substitute the first equation into the second equation:###
## Step 5Combine like terms:###
## Step 6Subtract 30 from both sides:###
## Step 7Divide both sides by 3:###
## Step 8Substitute
into the first equation:###
